Which of the following best describes Achal and Chal swaras in Indian classical music?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. Sa and Pa are fixed; others have variants like Komal or Teevra.
The Nature of Swaras
The seven notes (Saptak) are divided into two categories:
-
Achal Swaras (Fixed): Shadja (Sa) and Pancham (Pa) are immovable. They always remain in their natural (Shuddha) state and have no variations.
-
Chal Swaras (Movable): The remaining five notes—Re, Ga, Ma, Dha, Ni—can change their pitch. These are subdivided into Komal (flat) and Teevra (sharp) variants.
Key Breakdown:
-
Achal: Means "immovable." These provide the fundamental structural foundation for a Raga.
-
Chal: Means "movable." These allow for the diverse melodic textures found in different Ragas through pitch modification.
